are these really the only two flash carts for the gba? I was thinking about buying one, but I want to use it on the ds. I don't know if there are any problems with that. I'm kinda shocked by the price of the everdrive. I also read on here that they're redesigning the flash cart for release sometime this year., so should I wait? anyway, which one is the better of the two? I've read that the ez flash omega can corrupt saves if you don't leave the system on for about five seconds after having exited a game. is that still a problem? thanks.
